Migrating the corporate wide wireless authentication and authorization infrastructure to a new ISE implementation is something that causes MANY eyes to be watching and looking. Meraki's built in tools and packet capture capabilities allow the testing, and validation and POC's to be all done REMOTELY. We were up against a hard deadline. Then the current situation hit. The tools in Meraki's platform allow the implementation, POST validation and POST monitoring and validation to occur without a hitch. A few incidents tickets came in but the tools in the platform allow us to see that the issues were because the users were using improper wifi setup on the devices or bad credentials. Work smarter not harder. Thanks Meraki for letting this happen!

Hello, Thought i would save someone some frustrations if they are also working on the integration. Below is the modified transformation code we are using, it is slightly different from the published coded by cisco in the dev portal. You will see an added custom filed "service" we are injecting into the body object for the "Details". We also "null" out the "shared secret" we are using as a filter for incoming alerts to Pagerduty. On the SNOW side we are using the field to key off from other services to direct what ingest script to run. some of the documentation says to use the field 'title' but we found this did not work, but kept it in the code in case things change but its commented out. // Consume Meraki Alert via Webhook var body = PD.inputRequest.body; // Set Alert Severity var severity = "warning"; // critical // error // warning // info // unknown if(body.alertType == "Settings changed") {severity = "info";} if(body.alertType == "Motion detected") {severity = "info";} if(body.alertType == "Network usage alert") {severity = "warning";} if(body.alertType == "APs went down") {severity = "critical";} if(body.alertType == "Uplink status changed" && !body.alertData.uplink) {severity = "critical";} var event_type = "PD.Trigger"; //PD.Trigger - use this event type to trigger a new event //PD.Resolve - use this event type to resolve a triggered incident //PD.Acknowledge - use this event type to acknowledge a triggered incident //if (body.alertType == "APs came up") {event_type="PD.Resolve";} //var title = body.alertType+": "+body.networkName; var description = body.alertType+": "+body.networkName; var service = "Meraki Alert"; //add custom field of service to body object body.service = service; //var custom_details = body+"/:/"+service; // Format payload var cef_event = { event_type: event_type, //title: title, description: description, severity: severity, source_origin: body.networkId, dedup_key: body.alertId, service_group: body.organizationId, event_action: PD.Trigger, details: body } // Check secret and store event const SECRET = "secret123"; if(body.sharedSecret == SECRET){ body.sharedSecret = null PD.emitCEFEvents([cef_event]); }

So we are now getting alerts from Cisco Meraki via the webhook. This produces an alert and incident in Pagerduty. Which then assigns it to the right support group and through our API intergration with SNOW creating tickets in our incident management system. Having the Alerts come in near real time, has allowed us to see things we were not aware were going on in the environment!

Brilliant! the idea worked. the actual syntax is: // Check secret and store event const SECRET = "xxx123"; if(body.sharedSecret == SECRET){ body.sharedSecret = null <----- Blank secret from data (no brackets) PD.emitCEFEvents([cef_event]);

Hello, we have the meraki and pagerduty integration working using the custom code provided by cisco for the event transformation. we are using the "shared secret" as a filter for incoming alerts. now we are wanting to hide from the incident payload so that users/ticket do not see the "shared secret" anyone have any luck in doing this? we have tried the splice function and it did not work... here is the current code: / Consume Meraki Alert via Webhook var body = PD.inputRequest.body; // Set Alert Severity var severity = "warning"; // critical // error // warning // info // unknown if(body.alertType == "Settings changed") {severity = "info";} if(body.alertType == "Motion detected") {severity = "info";} if(body.alertType == "Network usage alert") {severity = "warning";} if(body.alertType == "APs went down") {severity = "critical";} if(body.alertType == "Uplink status changed" && !body.alertData.uplink) {severity = "critical";} var event_type = "PD.Trigger"; //PD.Trigger - use this event type to trigger a new event //PD.Resolve - use this event type to resolve a triggered incident //PD.Acknowledge - use this event type to acknowledge a triggered incident //if (body.alertType == "APs came up") {event_type="PD.Resolve";} //var title = body.alertType+": "+body.networkName; var description = body.alertType+": "+body.networkName; // Format payload var cef_event = { event_type: event_type, //title: title, description: description, severity: severity, source_origin: body.networkId, dedup_key: body.alertId, service_group: body.organizationId, event_action: PD.Trigger, details: body } // Check secret and store event const SECRET = "xxx123"; if(body.sharedSecret == SECRET){ PD.emitCEFEvents([cef_event]); }

You might want to also check the FW rules in the Meraki help section. The Apple systems manager is listed there.

I have "staged" upgrades to WIFI, switches, and FW's to different times and dates. GO to ORGANIZATIONS-FIRMWARE UPGRADE...then ALL NETWORKS. Time chosen will correspond to the timezone set on the network(s) chosen. Hope this helps,

one can already schedule different dates for the upgrades to occur. By "stage" are you referencing a set order/matrix to auto apply when new versions are released?

if you are using a self-signed cert in ISE, your users might be getting a warning on the cert before joining. a good test would be to try to join via an android phone that either has never joined and or delete the ssid (and cert) and see if it give you a cert warning.
